The daily use of the computer at the same time some friends may encounter is on the internet or just turned on the computer when prompted network cable was unplugged, such a phenomenon makes people very disgusted, the general phenomenon is not the computer network is not connected to the network is always interrupted, so that users can not carry out normal network applications, then how to solve such a phenomenon? Let's first analyze how we can create
The installation of the LAN starts from the cable, which is the most basic part of the network. According to statistics, about 50% of the network failure and cable-related. It can be seen that the quality of cable itself and the quality of cable installation directly affect the healthy operation of the network. In addi

The horizontal twisted pair wires in the cabinet are located on the rear side of the Cabinet. In the past, the twisted pair wires were not organized or simply bundled before being immediately mounted to the distribution frame. At that time, from the back of the Cabinet, the horizontal twisted pair wires were hanging like waterfalls, or several nylon cable ties can be bundled on either side of the Cabinet. Everyone is concerned about the performance te

Standard Organizations and manufacturers in North America and Europe have long been arguing over the selection and standards of the outer skin of Integrated cabling network data cables, just as they are still using FTP shielding products for UTP. Currently, North America, South America, Asia Pacific, and China all adopt the North America-based cable fire prevention standard UL and NEC (National Electrical Code ), in some parts of Europe, low halogen o
Maybe many people do not have a special understanding of the man optical cable line. Next we will introduce in detail the overall design and technical application of the man optical cable line. How to build a Metro optical fiber network? First, it should be based on the network structure of the man. Second, according to the construction idea of the man, the topology of the network should be flexible and cap

Recently I have had dinner with a few friends. We mentioned that because of the implementation of the new Labor Law, companies are gradually re-signing labor contracts with employees. Many of my friends are facing this

Article, where the information may have evolved or changed. [Ethereum Smart Contract] (http://upload-images.jianshu.io/upload_images/11831773-b4c4b20efddd1e04.jpg?imageMogr2/auto-orient/strip% 7cimageview2/2/w/1240) Ethereum is a distributed computing platform. It generates an encrypted currency named ether. Programmers can write "smart contracts" on the Ethereum blockchain, and these ethereum smart contracts are executed automa

I. Optical Fiber1. OverviewThe optical fiber is similar to the coaxial cable, but there is no mesh shielding layer. The center is the glass core of light transmission. In multimode optical fiber, the core diameter is 15mm ~ 50mm, roughly equivalent to the hair width of a person. The diameter of the Single-Mode Optical Fiber Core is 8mm ~ 10mm. The outside of the core is surrounded by a glass envelope with a lower refractive index than the core to keep
The energy-saving effect of the frequency conversion device is very obvious. The variable-frequency speed control motor is used in the high-power motor, and the entire generator set can save energy by 30%. After variable-frequency speed control is used, the soft start of the motor is realized to ensure smooth operation of the motor, reduce the wear and tear of the motor bearing, and prolong the service life and maintenance cycle of the motor. Therefore, variable frequency speed control technolog
1. Establish labor RelationsArticle tenth of this Law stipulates that the establishment of labor relations shall conclude a written labor contract . But in reality there are a lot of employers in order to evade the obligation, so that the labor relations in a state of uncertainty, in the event of labor disputes also can not be checked, often have not entered into a written labor contract situation occurs. I
Code contracts contain classes for tagging code, static analyzers for compile-time parsing, and run-time analyzers. System.Diagnostics.Contracts namespace.">The classes of code contracts can be found in the System.Diagnostics.Contracts namespace. The benefits of code contracts include:
Improved testing: Code contracts provide static contract validation, run-time checks, and document generation.
Automated testing Tools: You can use code contracts
just for a brief explanation-Spring Cloud Contract Validator is a tool that enables consumer-driven contracts (CDC) to develop JVM-based applications. It is provided in conjunction with the contract definition Language (DSL) . a contract definition is used to generate the following resources:

By reading this article, we can solve the following problems
What is a contract?
How many kinds of contracts are there? , what are they used for?
How do I define a contract?
is the contract independent of the platform?
What is the difference between a contract and a technology

Currently, cabling system installers and network technicians are still using older Cable Fault Locating tools based on analog technology that was just 40 years ago. Even tools that use these simulation technologies often identify cables incorrectly or cannot discover signals in common work environments, they are the only choice. This is the case until today.
